The correct combination is OCI Identity and Access Management (IAM) policies and OCI Logging. IAM policies are the precise mechanism to secure a custom model endpoint by defining which users, groups, or services can invoke the model, while OCI Logging captures every inference request payload and response for a complete audit trail. This pairing directly addresses the need for both access control and detailed logging of model usage, unlike OCI Audit, which only records administrative actions, or OCI Vault, which handles secrets. On the Oracle Cloud Infrastructure Generative AI Professional 1Z0-1127 exam, this question tests your ability to distinguish between services that secure the data plane (model inference) versus the control plane (management actions). A common trap is choosing OCI Audit because of its name, but remember: Audit logs who changed a policy, not who asked the model a question. For a quick memory tip, think “IAM locks the door, Logging records who walked through it.”
1Z0-1127 Using OCI Generative AI Service Practice Question
This 1Z0-1127 practice question tests your understanding of using oci generative ai service. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses OCI Generative AI to generate legal document summaries. They have a custom model deployed on a dedicated AI cluster. They want to ensure that the model is not used by unauthorized users. They also need to log all inference requests for auditing. Which combination of OCI services should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
OCI Identity and Access Management (IAM) policies and OCI Logging.
Option B is correct. OCI Identity and Access Management (IAM) policies control access to the model endpoint, and OCI Logging captures inference request logs for auditing. Option A is wrong because OCI Vault is for managing secrets, and OCI Audit logs administrative actions, not inference requests. Option C is wrong because OCI Data Safe is for database security, and OCI Monitoring tracks metrics, not logs. Option D is wrong because API Gateway with authentication and OCI Audit may not capture detailed model inference logs.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
OCI Vault for encryption and OCI Audit for logging.
Why it's wrong here
Vault handles encryption keys, and Audit logs API calls but not model inference details.
✓
OCI Identity and Access Management (IAM) policies and OCI Logging.
Why this is correct
IAM controls access, Logging records inference requests for audit.
Related concept
Static NAT maps one inside address to one outside address.
✗
OCI Data Safe and OCI Monitoring.
Why it's wrong here
Data Safe is for database security, Monitoring is for metrics, not detailed logs.
✗
OCI API Gateway with authentication and OCI Audit.
Why it's wrong here
API Gateway can authenticate but Audit does not log inference content.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 1Z0-1127 NAT questions on configuration and troubleshooting.
